Barker was inspired to include zombie training in the counter-terrorism summit after the Center for Disease Control introduced a campaign designed to remind citizens and soldiers to be ready for everything, zombies included.

The scenario, which Barker calls the Zombie Apocalypse, will feature undead actors that will attack participating troops and medical workers. HALO has partnered with Strategic Operations, Inc., a firm that specializes in using special effects and realistic combat training, to enhance the experience.

The Counter-Terrorism Summit will also train participants in a number of far less dangerous scenarios, including cyber warfare and Mideast combat.

Brad Barker sees the future of warfare being on the Internet.

"The new battlefield is cyberspace, for sure," he told the Military Times.
